Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Payload 是一个免费且开源的无头（headless）内容管理系统。在 3.88.0 之前的版本以及 4.0.0-canary.27 之前的 canary 版本中，如果攻击者能够查询一个可读的集合，控制其排序方式，并选择一个受保护的字段作为排序参数，就可能推断出该攻击者原本无法读取的字段值的有限信息。该问题已在 3.88.0 版本和 4.0.0-canary.27 版本中得到修复。
